Well, the ETA is under $150. If you want cheaper than that, the Safety 1st Avenue should work well. It's fairly narrow, will last a decent amount of time RF and FF for a 40# seat, nicely padded and has EPP foam. If you want cheaper than that, get a Cosco Scenera.

Cost issue aside, this kid is in 90s percentile in weight and height. Grandparents who will be using this seat are struggling with RF and are not getting the belts tight enough. This is why I want to turn the new seat front facing. I would rather have belts tight when they are using the seat that RF with weak belts.

So considering the weight and height, narrow seats are not an option (I don't think). Should I get another GN or something like Radian that many people seem to like?
